Odor Trap Segmented Water Seal Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional odor traps rely on a seal between the outlet connection and the odor trap to maintain a water seal, which can fail over time, leading to reduced service life and compromised odor isolation between the sewer system and the room.
Innovation Solution
The odor trap design includes a standpipe with an overflow opening, a siphon bell, and a sealing element that forms a gas- and liquid-tight seal independently of the outlet connection seal, using an inner pot and a spacer to maintain a water seal even if the primary seal is damaged, ensuring continuous odor isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal is used between the outlet nozzle and the odor trap to form the water reservoir, then the water seal is initially effective, but the seal deteriorates over time leading to reduced service life
Solution Approach 1:
The invention divides the odor trap into separate functional components: the water reservoir is formed by the inner pot and standpipe assembly, while the sealing function is provided by a separate sealing element at the base. This segmentation allows the water seal to be maintained independently of the outlet nozzle seal condition, resolving the contradiction between initial effectiveness and long-term durability.
Solution Approach 2:
The sealing element acts as an intermediary component that creates a seal between the standpipe and the outer pot base, rather than relying on the outlet nozzle seal. This intermediary sealing mechanism ensures that the water reservoir remains sealed even when the primary outlet nozzle seal deteriorates, thereby extending service life while maintaining reliability.
2Reliability
If the seal between outlet nozzle and odor trap deteriorates, then liquid leakage may occur, but the water seal and odor isolation should be maintained
Solution Approach 1:
The design separates the sealing function from the water reservoir formation function. The sealing element at the base provides a dedicated sealing interface between the standpipe and outer pot, independent of the outlet nozzle seal. This allows the water seal to remain intact for odor isolation even when the outlet nozzle seal fails, preventing liquid leakage through the segregated sealing path.
Solution Approach 2:
The sealing element is positioned at the base of the standpipe to provide a backup sealing mechanism before the outlet nozzle seal can cause failure. This preemptive sealing arrangement ensures that even if the primary outlet nozzle seal deteriorates, the water reservoir remains sealed, preventing liquid leakage and maintaining odor isolation reliability.
3Stability of the object's composition
If the outlet nozzle seal is compromised, then the structural integrity is reduced, but the water seal should remain intact
Solution Approach 1:
The water reservoir is constructed as a separate assembly with the inner pot and standpipe, sealed at the base by a dedicated sealing element rather than relying on the outlet nozzle seal. This segmentation isolates the water seal integrity from the outlet nozzle seal condition, allowing the water seal to remain stable even when the outlet nozzle seal is compromised.
Solution Approach 2:
The sealing element serves as an intermediary sealing mechanism between the standpipe and outer pot base, creating a stable sealing interface that is independent of the outlet nozzle seal. This intermediary seal maintains the water reservoir's structural integrity and prevents liquid leakage even when the primary outlet nozzle seal fails.
